[QGIS-Developer] QGIS 3 getComposerItemById should return subclassed item

[Etienne Trimaille]

The original snippet:

   @staticmethod
    def get_composition_item(comp, item_id, item_class):
        for item in comp.items():
            if isinstance(item, item_class):
                if item.id() == item_id:
                    return item
